Anyone ever do IV infusions?

So My friend has a IV medical infusion clinic that does IV fluids with Multivitamins in it he does these transfusions on pregnant women all the time OBs actually refer patients to them. Iv been constantly sick and my body has literally been rejecting all sources of protein. Even if I take Zofran every 8 hours I’m still puking. My Ob sent me to the ER for fluids before and they helped like crazy. I’m thinking about doing these infusions because they Contain the same vitamins that are in ER fluids just adds B12. Hes offering then the next for free. My twins are 18 weeks and one has a lower weight then the other. Dr thinks it’s cause I can’t get any protein down me. Anyone ever use them and did they help at all?
